NAME Acme::CPANModules::CheckingModuleInstalledLoadable - List of modules to check if a module is installed or loadable VERSION This document describes version 0.002 of Acme::CPANModules::CheckingModuleInstalledLoadable (from Perl distribution Acme-CPANModules-CheckingModuleInstalledLoadable), released on 2023-08-06. DESCRIPTION If you simply want to check that a module's ".pm" file is locatable in @INC, you can just do something like: my $mod = "Foo/Bar.pm"; for my $dir (@INC) { next if ref $dir; if (-f "$dir/$mod") { print "Module $mod is installed"; last; } } Or you can use something like Module::Path or Module::Path::More which does similar to the above. A module can also be loaded from a require hook in ~@INC~ (like in the case of fatpacked or datapacked script) and the above methods does not handle it. Instead, you'll need to use Module::Load::Conditional's "check_install" or Module::Installed::Tiny's "module_installed": use Module::Load::Conditional qw(check_install); if (check_install(module => "Foo::Bar")) { # Foo::Bar is installed } The above does not guarantee that the module will be loaded successfully. To check that, there's no other way but to actually try to load it: if (eval { require Foo::Bar; 1 }) { # Foo::Bar can be loaded (and was loaded!) } ACME::CPANMODULES ENTRIES Module::Path Author: NEILB Module::Path::More Author: PERLANCAR Module::Load::Conditional Author: BINGOS Module::Installed::Tiny Author: PERLANCAR FAQ What is an Acme::CPANModules::* module? An Acme::CPANModules::* module, like this module, contains just a list of module names that share a common characteristics. It is a way to categorize modules and document CPAN. See Acme::CPANModules for more details. What are ways to use this Acme::CPANModules module? Aside from reading this Acme::CPANModules module's POD documentation, you can install all the listed modules (entries) using cpanm-cpanmodules script (from App::cpanm::cpanmodules distribution): % cpanm-cpanmodules -n CheckingModuleInstalledLoadable Alternatively you can use the cpanmodules CLI (from App::cpanmodules distribution): % cpanmodules ls-entries CheckingModuleInstalledLoadable | cpanm -n or Acme::CM::Get: % perl -MAcme::CM::Get=CheckingModuleInstalledLoadable -E'say $_->{module} for @{ $LIST->{entries} }' | cpanm -n or directly: % perl -MAcme::CPANModules::CheckingModuleInstalledLoadable -E'say $_->{module} for @{ $Acme::CPANModules::CheckingModuleInstalledLoadable::LIST->{entries} }' | cpanm -n This Acme::CPANModules module also helps lcpan produce a more meaningful result for "lcpan related-mods" command when it comes to finding related modules for the modules listed in this Acme::CPANModules module. See App::lcpan::Cmd::related_mods for more details on how "related modules" are found. HOMEPAGE Please visit the project's homepage at . SOURCE Source repository is at .

Most of the time, you don't need to build the distribution yourself. You can simply modify the code, then test via: % prove -l If you want to build the distribution (e.g. to try to install it locally on your system), you can install Dist::Zilla, Dist::Zilla::PluginBundle::Author::PERLANCAR, Pod::Weaver::PluginBundle::Author::PERLANCAR, and sometimes one or two other Dist::Zilla- and/or Pod::Weaver plugins. Any additional steps required beyond that are considered a bug and can be reported to me. COPYRIGHT AND LICENSE This software is copyright (c) 2023, 2019 by perlancar .
